The root cause of all our suffering, is our mistaken understanding of reality. We are suffering not because we are “bad” but because we are ignorant. The more we are able to attune with reality, the happier we will be. The Heart Sutra mentions that the Bodhisattva has “gone beyond sorrow” – he or she has attained lasting happiness through understanding the emptiness of inherent existence of all phenomena. While it could take a lifetime to understand this, even a small understanding can help us to be happier.
